DUPLICATING-MACHINE.

Specification of Letters Patent- Patented Nov. 19, 1918.

Application filed June 12, 1913; Serial N o. 273,192.

To all whomc't may concern:

Be it known that I, KATHERINE R. OKANE, a citizen of the United States, re-

siding at Philadelphia, in the State of Penn-- My improvementis particularly applicable to printing machines of the type known commercially as the Multigraph comprising a rotary printing cylinder having a series of undercut channels, in its perimeterextendlng parallel with lts axis to receive complementary shaped flanged type which said cylinder presents in opposition to the other member of the. printing couple. ordinarily constructed, the only means with which such a machine is provided forprinting lines at right angles to the lines of letter type consists of type fitted to the channels and'having dash faces. Consequently, a series of such separate type must be usedto print a line of greater extent than the dash carried by the face of a single type, and, unless said line type are accurately set and provided with means to hold them in alinement they print a broken line instead of the continuous line desired.

Therefore, it is the object of my invention to provide such a machine with means to present a continuous printing face to print lines at right angles to the lines of .words,

and as hereinafter described such means includes a rule strip curved to fit circumferentially upon said printing cylinder and preferably having means fitting in said undercut channels thereof adapted to retain it in set position.

My invention comprises the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawings; Figure -I is a side elevation of a rotary printing cylinder and a reciprocatory plane platen, such as are employed in a machine of the type specified.

Fig. II is a fragmentary plan view of a portion of said cylinder with letter type and rule strips set therein.

Fig. III is an end view ofthe elements shown in Fig. II.

Fig. IV is a detached view of a complete rule. strip such asshown-at the lefthand Asv side of Figs. II and III, but on a smaller scale.

Fig. V isa detached view of a complete rule strip such as shown at the right hand side of Figs. II and III, but on a smaller scale. I

Fig. VI is a sectional view of said strip taken on the line VI, VI, in Fig. V.

Fig. VII is a vertical transverse sectional view of a rotary printing cylinder showing amodified form of my invention.

Figs. VIII and IX are fragmentary vertical transverse sectional views (if a printing cylinder showing different modified forms of my invention.

Fig. X is a fragmentary longitudinal sectional view taken on theline X, X, in Fig. VII, but on a larger scale.

Fig..XI is a fragmentary longitudinal sectional view taken on the line XI, XI, in Fig. IX.

Fig. XII is a fragmentary elevation of one endv of a rule strip, resembling that shown in Fig. VII, but having its printing surface in unitary relation with its supporting band, likethe strip shown in Figs. II, IIIand IV.

The-rotaryv printing cylinder 1, has the undercut channels 2, extending in its perimeter parallel with its axis, and, each type 3, 4, and 5, is provided with flanges 6 complementary to and fitted in said channels. The rule strip 8 beingcurved to fit the circumference of said cylinder 1 is held-thereon between said type merely by frictional engagement of its flanges 9 therewith; said type being clamped together in the direction of the length ofthe lines of words by any suitable means. However, the rule strip 11 which is likewise. curved to fit the circumference of saidcylinder 1 and provided with flanges 12 for engagement between said type, is also provided with lugs 1 1 which fit in said undercut channels 2 soas to be retained by the overlapping ledges 15 engaging the flanges 16 on said lugs; so that said strip 11 may be retained on the cylinder independently of said type. 5

It may be observed that the flanges 9 and 12 of said strips 8 and 11, which extend in I find it convenient to make the rule strips above described, by rolling them from brass or other suitable metal with the respective flanges 9 and 12 thereof straight.

and then curving said strips to fit said cylinder, by another rolling operation.i HOW"...

ever, it is to be understood that said strips may be otherwise manufactured, for instance, they may be cast of ordinary type metal or other suitable material.

When the type have been assembled in said cylinder 1 in the desired relation the inked ribbon 20 is drawn over the type faces and secured by connection with the rollers .21 and 22 which are mountedin said cylinder as indicated in Figs. I and VII, so that when a sheet of paper is interposed between the platen and said cylinder and the latter turned until the platen is shifted to the position shown in dotted lines in Fig. I, said sheet .,is imprinted with an impression made from said type and rule strips through said inked ribbon. Y

The rule strips above described have printing surfaces which are in rigid relation with their supporting flanges extending laterally upon opposite sides thereof and bearing upon the printing drum, and the means connecting said strips with said drum independently of said type are rigid portions of said strips. However, it is to be understood that the printing surfaces of the stripsmay be resilient and that separable and resilient means may be employed for connecting the strips with said drum. For instance, as shown in Fig. VII the printing surface of the rule strip 25 is a cord connected with and carried by 'the band 26, conveniently formed of sheet metal,

which forms supporting flanges extending laterally upon opposite sides of said print mg surface 25 as shown 1n Fig. X. I prefer to connect said printing surface. 25 with said band 26, intermediate of its length, by means 27 adhering to both of said elements. However, it is to be understood that said printing surface 25 may be formed by'a cord or wire which may be attached to said band only at its ends, or intermediate of its length as indicated in Fig. X. Said rule strip shown in Fig. VII has no means connecting it with said drum by engagement in said channels 2, but is connected with said drum by the resilient hooks 29, conveniently formed of wire, pivotally connected with said band 26 by extension through the bights 30 at the ends thereof. Said hooks extend beneath said outer curved surface of the drum which is formed to carry the type, in engagement with the sectoral ledges 31 of the drum, and it is to beunderstood that said hooks are flexible and resilient not only in the direction necessary for them tween .theindividual type 3 set in said channels 2. However, as above described, said rule strip has means connecting it with said drum 1 independently of said type.

Although I have shown said rule strip in Fig. X as formed of two primarily separate elements respectively constituting the print-. ing surface 25 and the supporting flanges 26; it is to'beunderstood that said elements may be in unitary relation as indicated in Fig; XII,.wherein they are pressed from a single-strip of sheet metal. Moreover, although I have shown the severalrule strips aforesaid with their printing surfaces 25 coextensive with their supporting flanges; it 'isfto be understood that they may be made of less extent. However, it is obvious that unless the printing surface thereofis coextensive with a plurality of the type" channels 2 and the rows of type set therein, itwould be more convenient to employ a single column'dash type of the prior art; the advantage of my, invention being that the column rule may'be formed in accordance therewith'which is less costly than a column rule formed of such dash type and which may be set in a fraction of the time required to set a column rule formed of such type.

Of-course, if said printing surface '25 of the rule strip last described be formed of cord, it would be resilient, but if formed of wlre it'would'not be resilient, assuming that its supportingband 26 be in intimate contact with the curved surface 32 of the drum. However, as indicated in Fig. VIII the printing surface 34:, which may be formed. 1

of wire, is resiliently supported by the band 35, conveniently formed of rubber. The

rule strip having said printing s'urface 3l curved in concentric relation with the drum 1 may be held between said flanged type 3, 4, and 5 as above described, but is also provided with end lugs 36 fitted in said channels 2 and having flanges 37 engaged by the overlapping ledges 15 in said channels. Said rule strip is also provided with sepa-' rable and resilient means for connecting it with said drum, including the wedge blocks 39 which are conveniently formed of molded rubber. Said resilient band 35 is also conveniently provided with end lugs 41 ex tending into saidchannels 2 and conveniently secured by the wedge blocks 42 which may be separable and resilient like said blocks 39. I

As shown in Figs. IX and XI a rule strip having a printed surface 45 may be formed of a cord or wire without supporting flanges bearing upon the surface of the drum although curved in concentric relation with the latter; said strip being supported by the blank space type 5 and projecting above the latter to the same extent as the printing faces of said type 3 and 4. Said rule strip having the printing surface 45 is provided with lugs 46 extending in the channels 2 and having the flanges 47 engaged beneath the overhanging ledges 15 in said channels. Said strip is also conveniently provided with separable and resilient means for connecting it withsaid drum independently ofsaid type, including the wedge blocks 49.
